Sigma Design vs USA Firmware: overview
Sigma Design
Sigma Design (operating as SIGMADESIGN) was established in 1994 in Portland, Oregon and is now headquartered in Camas, Washington with approximately 283 employees across five continents. Its stated scope covers mechanical design and engineering, industrial design, testing, onsite contracting, and software and firmware engineering, positioning itself as a full product design and engineering partner rather than a firmware-only vendor. For an RFP that groups industrial design, mechanical engineering, and firmware into one deliverable, Sigma Design's breadth and headcount give it more parallel-program capacity than most boutique bidders on this list.
USA Firmware
USA Firmware was founded in 2011 by Bob Scaccia and operates from Brecksville, Ohio with a team of around 17 people. Its managed design services bundle electrical engineering, firmware, FPGA design, embedded software, and Linux expertise into a single discovery-through-production-enablement process, positioned for buyers who want one accountable vendor rather than coordinating separate electrical, firmware, and FPGA contractors on an RFP. Leadership brings a stated 150-plus combined years of experience concentrated in a small, senior team.

Sigma Design vs USA Firmware: pros and cons
| Sigma Design | |
|---|---|
| + | 283 employees across five continents give substantially more parallel-program capacity than most boutique firms on this list |
| + | 31 years of operating history under continuous product-design focus |
| + | Industrial design and mechanical engineering sit alongside firmware, matching how a full product RFP is often scoped |
| + | Onsite contracting option can place engineers directly with a client team for close-coordination programs |
| - | Firmware is one discipline inside a much broader product-design practice, not the firm's primary specialty |
| - | No published pricing or minimum engagement figure |
| - | Public case studies specific to firmware-only engagements, versus its broader product design portfolio, are limited |
| USA Firmware | |
|---|---|
| + | Leadership brings a stated 150-plus combined years of experience concentrated in a small, senior team, a strong bench-quality signal for a smaller RFP |
| + | Bundles electrical engineering, firmware, and FPGA design under one managed process, matching how a mid-size RFP often wants a single accountable vendor |
| + | Discovery-through-production-enablement scope covers the full program, not just firmware coding |
| + | 14 years of operating history under its founder |
| - | 17 employees is among the smallest teams on this list, limiting fit for an RFP requiring large parallel workstreams |
| - | Public case study detail is limited, so verifying past client work requires direct reference outreach |
| - | No published pricing or minimum engagement figure |
